Rated 5 out of 5 by from Plenty of bang for the buck. Bought at a common big-box home improvement store for $1800 and change (including the upgraded 10 year warranty)....much cheaper than the staggering $4899 suggested list on the website. Installed easily. I did it "hot" so as not to need inspections or involve power company by pulling meter. Spent about $150 on some flex conduit, wire, fittings, etc. Had trouble getting it to connect to WiFi,. Spent two hour plus long sessions on phone with customer service ladies who were clearly working from home. They were nice ladies... friendly and did their best, but they were clearly working off a script or flowchart, and I would rather talk to someone who has had their hands dirty installing one before.. Ultimately she told me i needed 2 GHZ wifi when I was using 5 Ghz.. Bought a repeater to separate the bands and now I'm good. Also bought the option lifting hole plastic covers for a better finished appearance.

Rated 5 out of 5 by from Great product, installation & service! Kudos to Stuller Power Solutions in Hendersonville, NC from start to finish, who I was referred to by a friend & fellow customer. Brian Stuller, the owner came to our home to assess our specific needs, followed by his excellent install team Jeremy & Austin with the final set up/operation by highly experienced Mike who took the time to educate in operation. Highly recommend!

Rated 1 out of 5 by from Poor Choice We purchased and had installed a Generac 14KW whole-house backup power system in late 2022 for our newly built home in Columbia CA. The Generac system was recommended by the electrician who wired our house and unfortunately we didn’t question his recommendation or look at other manufacturers. During a power outage in November 2023, the engine which had only 9.7 hours, failed, producing lots of oil smoke and oil residue on the interior and exterior cabinet and on the ground. A Generac qualified technician determined that a ring had probably failed. Instead of replacing the entire oil contaminated unit, he ordered a new engine. After waiting for several weeks without backup power, the new engine arrived and it took the technician the better part of a day to remove the old engine and replace it in the oil contaminated cabinet. He attempted to start and run the new engine without success. It too was defective with no compression in either cylinder. And this engine had been built up new at the factory specifically as a replacement for the original engine. Another engine was ordered. We are now two months without backup power and the third “new” engine was just installed. The technician wants us to run it for two hours to get it hot to allow the rings to break in and seat the valves. And we may need to wipe off some “excess oil” at the exhaust louvered vent. Our responsibility. We will see just how reliable over the next months and potentially years, this product will be. I don’t have a whole lot of confidence right now but it seems we’re stuck with it. I am very disappointed in this Generac product and would not have purchased it knowing what I know now. To anyone considering purchasing a Generac home backup power system, do your due diligence before spending so much money on this brand. Check ratings on consumer sites in addition to this one before purchasing. I wish that I had.

Rated 5 out of 5 by from Best Invesment Ever! - Part 2 I had my 14kw generator installed in September of 2022. I wrote a glowing review a year ago when the generator flawlessly got us through a power outage over Xmas in 2022. I wanted to follow up with another review. You may have read about the big wind storm in Maine this December where 1/2 million Mainers lost power. Our power was out for 4 full days. Again, our generator performed perfectly. The temperatures dipped into the teens but we had zero discomfort. We had running water (we have a well pump), oven, electronics, etc.... I have been good about maintenance, load-testing, and daily oil checks when the generator is running but the generator has consistently delivered as promised. Again, I couldn't recommend it more.

Rated 2 out of 5 by from Wifi is a LIE The generator itself seems to be ok. BUT Multiple hours on the phone with customer service. First it said I had entered the Serial Number and MAC address wrong. I didn't, and later Customer service agreed I had entered it correctly. We tried everything she could think of to get the unit to communicate. She said the problems with the ap are known and they are working on fixing it. I expect better from a US company. To me it's real plain. DON'T SELL YOUR PRODUCT UNTIL IT PASSES QUALITY!
